1. A medical suction device comprising:
a main body being composed of a rigid material, the main body having a suction channel formed therein, the main body having a distal end and a proximal end for connection to a vacuum source, the suction channel having an open distal end and a proximal end for connection to the vacuum source;
a detachably attaching distal nozzle being mounted on the distal end of said main body, the distal nozzle being composed of a semi-flexible material,
wherein said distal nozzle is configured to make contact with a foreign body or debris for extraction from a surgical field;
wherein said distal nozzle includes a distal end and an opposite proximal end for connection to the main body, the nozzle comprising a nozzle conduit terminating at an open distal end and having a proximal end that fluidly communicates with the suction channel of the main body, wherein the distal nozzle has a liquid chamber defined therein at the proximal end that acts as a reservoir for liquid, the liquid chamber being located distal to the distal end of the main body; and
a movable flow stopper that is disposed within the liquid chamber distal to the distal end of the main body and is configured to allow flow of the liquid in a proximal direction towards the suction channel, while restricting flow in a distal direction within the nozzle conduit.
